EXPLANATION. 


In.  the  following  tables  the  first  column  on  each  page  contains  the  Constant  from 
o".oi  to  o".5o,  inclusive. 

The  remaining  columns  contain  the  Corrections. 

The  argument  is  the  declination  of  the  star,  and  is  found  at  the  top  of  each 
column  of  the  Corrections. 

The  correction  for  azimuth  is  denoted  by  Aa. 
The  correction  for  level  is  denoted  by  Bb. 
The  correction  for  collimation  is  denoted  by  Cc. 

For  the  methods  of  determining  the  values  of  the  factors  A,  J3,  and  C,  and  the 
constants  a,  I,  and  c,  see  "  Introduction  to  the  Observations  with  the  Transit  Circle,

U.    S.    NAVAL    OBSERVATORY. 


EXPLANATION    OF    TABLES. 


In  the  following  tables  the  first  column  on  each  page  contains  five  values  of  the 
Constant,  and  the  remaining  columns  contain  the  corresponding  Corrections.

For  the  methods  of  determining  the  values  of  the  /actors  A,  ti,  and  C,  and  the 
Constants  a,  b,  c,  see  "Introduction  to  the  Observations  with  the  Transit  Circle,  1870."
